Abstract: The present invention discloses a selective and a non-selective method and means of treating microbial diseases in local infections. The novel method comprising the step of emitting a beam of a blue light towards the tissue to be treated, wherein the beam is having a wavelength from 400 to 550 nanometers and further wherein the temperature of said tissue is not exceeding about 42° C. along the procedure or immediately after it so that a selective phototoxic effect is exerted. A cost effective device for selectively or non-selectively exerting phototoxic effect by emitting a beam of blue light towards a tissue to be treated is also provided useful, especially for dental application.

Abstract: The present invention concerns the use as anti-viral agents of isolated fractions from berry juice of the plant genus Vaccinium. Two specific fractions are provided: (a) polymeric material having a molecular weight ?12,000; and (b) proanthocyanidins-containing fraction. Thus, the invention provides methods of treating a subject against a viral infection; the method comprises providing said subject with at least one of the above isolated fractions in an amount effective to prevent production of a viral infection in said subject. A specific and preferred viral infection according to the invention is an influenza virus infection.

Abstract: A non-food anti-microbial-adhesion and aggregation composition comprising a suitable carrier and an effective amount of an adhesion inhibitory fraction isolated from juice from berries of the Vaccinium plant genus. In an embodiment the anti-aggregation and adhesion fraction is isolated from cranberry juice. It is characterized as being polymeric and having a molecular weight ?14,000; an elemental analysis of carbon 43-51%, hydrogen 4-5%, no nitrogen, no sulfur and no chlorine; a nuclear magnetic resonance (NMR) line spectrum as set forth in FIGS. 2A and 2B; and an ultraviolet spectrum with an absorption peak at 280 nm in neutral or acidic pH solution which is absent in alkali solutions. This fraction exhibits adhesion inhibitory activity against P fimbriated bacteria, oral bacteria and Helicobacter pylori.

Abstract: Dental apparatus includes a tank of compressed sterile oxygen, or another compressed gas such as nitrogen, a source of a pressurized treatment liquid, and valves for coupling the oxygen tank or treatment liquid to the water inlet of the dental unit enabling the dental unit to be used for a wide variety of dental treatments, particularly when using a triple syringe for rinsing the canals in root canal treatment, or when using an ultrasonic scaler for dislodging hard deposits and stain.

Abstract: A method for detecting and localizing bacterial growth on a surface comprising the steps of:(a) applying a solid substrate to the surface;(b) removing said substrate from said surface and incubating said substrate for purposes of facilitating ultimate visualization of selective bacterial growth; and(c) observing the locus of bacterial growth on the substrate.The method is particularly effective in detecting and localizing cariogenic activity in the mouth.

Abstract: A handheld dental tool for crown preparation, comprises a handle, a grinding burr, and a guard attached to the handle. The guard has a tip solid spherical closely spaced from the tip of the grinding burr such as to be receivable between the tooth to be prepared and the free gingival tissue thereat to protect the gingival tissue during the grinding of the tooth.

Abstract: Microorganism culture transfer devices are described of the type comprising a manually-grippable handle having a culture contacting tip for contacting a culture and streaking same a plurality of times over a culture plate in order to dilute the culture for purposes of isolating individual colonies. The handle is of a configuration in cross-section defining at least three, preferably four or more, discrete rotational positions when held and rotated by the user's fingers about the longitudinal axis of the handle; and the culture-contacting tip is of a configuration such as to provide a different and distinct surface for contact with the culture in each of the discrete rotational positions of the handle.
